কীভাবে Pentagonal Prism গণনা করবেন
Pentagonal Prism কি?
A pentagonal prism has two regular pentagonal bases and five rectangular lateral faces. It has 10 vertices, 15 edges, and 7 faces.
সূত্র
A_base = (a²/4)√(5(5+2√5)); V = A_base × h; TSA = 2A_base + 5ah

ধাপে ধাপে নির্দেশিকা
- 1Base area = (a²/4)√(5(5+2√5))
- 2Volume = Base area × h
- 3Lateral surface = 5 × a × h
- 4Total surface = 2 × Base + Lateral
